Beautiful Avanti….Enjoy!

Received the latest issue of ‘AVANTI MAGAZINE’…. Great reading, as usual, however I was a bit disappointed in not seeing the follow up story about the ‘Due Cento’ Studebaker Avanti…. Perhaps next issue?

You got it! (actually, the factory bulletin stated this may happen at any engine speed over 1500 RPM.)

One thing I forgot to mention while we’re on this subject….I’ve had good luck with the factory Stude Avanti R1&R2 automatic choke system…HOWEVER!… There are two adjustments that need to be made at the plastic choke cover… a summer adjustment and then a winter adjustment…. (At least for those of us living in hot/cold climates) My ‘63 R2 works best with the choke cover rotated to the ‘three lean’ position for winter operation… and then to the index mark or one rich for summer start up….. of course, all engines/carbs behave slightly different… but my Avanti seems to run best using those settings!

Suggestion… don’t remove/alter any of that original wiring… just tie it back using wire ties….. Unless you are going to ‘show’ your Avanti and do it for esthetics, I believe you’re better off leaving it all intact…. Just unplug and remove the electronic control module….and either manually (or through the use of the many aftermarket kits available) activate your lockup torque converter. I did the above when eliminating electronic engine controls on my own ‘83 Avanti, which I use for everyday transportation, many years ago… and have had no problems whatsoever! (also…remove the fuse at fuse box sending power to the ECM…. and, of course, you will need a non electronic controlled distributor and carburetor)

Wow!!!… Really, really nice !!!!!

I installed that same Ford type power steering pump cover on my ‘63.. Very convenient! You’re probably thinking of updating to a dual brake master cylinder?

Looks good!!!

Exactly Correct!!

Hi Paul… someone more knowledgeable may chime in on this, but in my opinion ‘Avanti Black’ was a legitimate option from the ‘get go’…. only to be discontinued, and then brought back as an extra cost option. If you’re asking what was the serial # of the first production Stude Avanti painted black… I haven’t a clue! Paul S, by the way, owns a gorgeous ‘Avanti Black’ ‘63 Avanti R1

Studebaker engineers identified an occasional ‘flat spot’ when throttle pedal was floored on some of the supercharged (only) Avanti engines at engine speeds above …..?…… RPM. 1) 900……2) 1500……3) 2000….or….. 4) 2500

Carburetor choke thermostatic springs & housings are not the same on R1 and the R2 Studebaker Avanti engines…..True?

I would add that the evaluation of this poster’s choke problem, and my thoughts on how to properly correct that problem, are based on the assumption that the carb itself is in good adjustable condition…… If the carb is ‘worn out’ (sixty+ years old!), and the throttle shafts are loose in their bores, etc., it would be better, in my opinion, to ship the carb to a qualified rebuilder… or, go the modern Edelbrock route.

As most of us Stude Avanti (and early Avanti ll) owners already know, many of the Carter AFB carbs on these cars have been ‘tinkered’ with over the years. That fact is why some owners replace these factory carbs with new production Edelbrock versions… and call it good. However, for those of us who prefer to keep the original carb on our Avanti’s, it’s a good idea to obtain a relevant shop manual, and adjust that carb back to spec… Pay careful attention to the side linkage rods, as some folks tend to bend them when attempting to make adjustments, throwing everything off. In colder climates, make sure you have an exhaust heat riser valve in place and working… and that the proper intake manifold gaskets are installed…. Also, internal vacuum passage in these AFB’s must be open for heat to be drawn up into the choke housing.. normally happening rather quickly.

I’m all for mods that truly improve the function and drive ability of our Avantis. However, in this case I hate to see folks misled in thinking that a vacuum choke pull off is a good idea, when what’s actually going on is simply a misadjusted carb, or defective peripheral controls…. I understand these early AFB’s “pretty good”! Your vacuum choke pull off adaption does look well thought out though…. and I complement you on that….Ed
